Compute precise cable tray offset geometry, run lengths, and diagonal travel dimensions for tray routing elevation changes. Supports multiple engineering units for NEC and IEC industrial electrical installations. Calculate true diagonal travel lengths, horizontal runs, and bend geometry for ladder. To manage changes to cable tray or conduit when elevation changes Select the segment you want to modify. This guide covers the critical steps, from selecting the right electrical cable tray and performing accurate cable fill. I've linked two photos, the first one shows a ladder cable tray that has been placed on top of a mezzanine, with the middle elevation being 12'-6", but then I go and place another ladder cable tray like 3 feet directly above it but for some reason it tells me that its middle elevation is about. en completely installed, without damage either to conductors or structural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
